Very bad news - condolences to Tom's family and friends. I was hoping he'd be found with maybe a bum leg and a case of the shivers, but sadly not.
The meet-up itinerary had them going up and over NAP and returning the same way. If he was found at AP, I wonder if that irritating uphill pull on the return over NAP caused him to deviate? He certainly wouldn't have been the first to bypass it by going to AP instead, especially since the snow is virtually gone.
